REMAINS. TV 11 NEWS. IT IS WITH SADNESS TONIGHT THAT WE NOTICE THE PASSING OF BOOKMAKING GREENBERG, WHO DIED AT THE AGE OF 20. SOME WOULD CALL HER A MEDICAL MIRACLE. SHE DID NOT AGE PAST THE MIND AND SIZE OF A BABY. WE HAVE BEEN FOLLOWING HER AND HER FAMILY FOR MORE THAN 10 YEARS. WE FIRST MET THEM BACK IN 2001. SHE WAS BORN WITH A RARE UNKNOWN CONDITION, WHICH MEANT SHE DID NOT AGE. AT ABOUT FIVE, SHE SIMPLY STOPPED GROWING. FOUR YEARS LATER, SHE HAD NOT GAINED A POUND OR AN INCH. SHE HAD THE MIND AND BODY OF A NINE-MONTH-OLD BABY. DOCTORS EVENTUALLY CALLED IT "SYNDROME X." THEY BELIEVE SHE IS THE ONLY PERSON IN THE WORLD WHO HAVE IT. THE OLDER SHE GETS, THE MORE UNBELIEVABLE IT GETS. EVERYBODY WANTS TO HOLD HER. SHE LITERALLY IS THE FOUNTAIN OF YOUTH, IF YOU THINK ABOUT IT. SHE HAS SHOWN ME THAT. THAT IS WHAT SHE IS HERE FOR.
